WILLIAM C. BUSSEY, OF JACKSON, CALIFORNIA.

LOCK.

Specification forming part of Letters Patent No. 49,712, dated September 5, 1865.

To all 'whom 'it may" concern Be it known that I, W. G. BUssEY, of Jackson, in the county ot' Amador and State of California, have invented a new and Improvedv Burglar-ProofLock; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and u se the same, reference being had to the accompanying drawings, forming part of this specication, in which- :Figure 1 is a rear view of my invention; Fig. 2, a section ot the same, taken in the line v'at .'r, Fig. 1; Fig. 3, a detached perspective view of one of the arms by which the bolts are moved; Fig. 4, an outenface view ot' the ratchets by which the tumblers are adjusted; Fig. 5, an inner-face view of the same; Fig. 6, a section vot' Fig. 5, taken in the line y y. Y

Similar letters of reference indicate like parts.

This invention relates to a new and improved lock of that class in which .a series of rotating annular tumblers are employed; and it consists i n a -novel arrangement ot' such tumblers in .connection with arms (one or more) connected with one or more bolts, substantially as herein shown and described, whereby an extremely simple and etticient burglar-proof lock is obtained'. t A represents the case ofthe lock, which may be ot' any suitable or desirable form, and containing, in the present instance, two bolts, B B,- one of which is shown thrown out from case A to the position it occupies when the lock is These bolts are operatedthrown ont and drawn into the case A--by means ofarms C C, which are ot' curved form,

as shown in Figs. 3 and 5, and have tubularv arbors D at one end, which pass through the outer plate of the lock-case, and have knobs applied forV the convenience ot' turning them, said arms being connected by pins a with the bolts B, the pin-holes in the bolts being some- Hwhat oblong, in order to admit ot the pins a making the necessary curvilinear movement from the arbors D as centers, and to operate or move the bolts. The dotted lines in Fig. l show the form ofthe pin-holes. The inner'snrfaces of the arms C C, at or near the ends which are opposite to those where the arbors vided with ratchet-teeth c at their inner sidesonly. The outer sides ot' the rings E E have each a spring-pawl, F F', attached. The pawl F of the ring Eengageswith the teeth c at the inner side ot' E, while the pawl'F' of l the ring E engages with the teeth o at the inner side ot' the ring E'. Within the ring E" there is a cylinder, E, which has a spring-pawl, F, attached to its periphery, said pawl engaging with the teeth c at the inner side of the ring E". The teeth of the ring E', it will be seen, have a reverse position to those ot' the ring E", and the outer ring, E, is prevented from turning in one direction by means of a pawl, d, secured within the lock-case. Each set of teeth of the several rings is provided with a long tooth, c, the object ot which will be presently explained.

The several rings E E E", as well as the cylinder E, are provided with flanges f, to ad, mit of the rings and cylinders forming an overlap with each, so .that they will be kept in place, (see Fig. 6,) and the inner surfaces ofthe rings and cylinder are each provided with an annular ledge, g, said ledges forming tumblers. These ledges have each a break orl recess, h, in them, as shown clearly in Fig'. 5. These annular tumblers g fit in the notches b ot' the arms C C, through the medium or" which the bolts B B are moved, and the ledges g prevent the movement of said arms and bolts. The only way in which the bolts can be moved is to turn the rings E E E and cylinder FH so that the several recesses h ot' the tumblers will be brought in line with each other and the arm (l, and the latter may then be moved, and consequently the bolt connected with it. These tumblers are moved or adjusted so that one bolt may rst be moved and then the other. Some locks may be constructed with one bolt only. Two, however, will make a more secure The several rings E! E" and cylinder E are turned as follows: Gis a circular plate, having two holes, t' i, made in it to receive pro tion of arrow 2, the pawl F of ring-El catching (See Fig. 4.) TheA into the inner teeth ofE. ring El is turned separately or without Eby turning `the arbor H in an opposite direction, as indicated by arrow 3. turned by turning the spindle I in the direction indicated by arrow 4, the` pawlFi/of cylinder Emengaging with the teeth of ring E,

While the cylinder E" is moved yseparately without E by turning the spindle Ain the opposite direction, as indicated byvarrow 5. The large tooth of each ring or set vof teeth is for the'purpose of indicating the position ofthe several rings and .turning them in the proper place, the clickv of the pawls, in passing over the short teeth, enabling the operator to adjust the rings properly, the number of clicks being counted from the large tooth.

The spring E" isl The rings may be set and turned by figures or by the letters of the alphabet, or by words Various modes may, bedevised for Aenabling the recesses h to be brought in line 'with each other, and I do not confine myself to anyparticular Inode.

This arrangement admits of an indetlnte number of chan ges being made. The lock atthe same time may be constructed at a moderate cost.

4I claim as new and desire to secure by Leiters Patentl l. The employment or' use of a series of rings, EE E, and a cylinder, E", provided respectively with teeth'and pawls, and also with annular tumblers g, to operate in connection with notchedarms C, through which the bolts B are moved, substantially as and for the purpose set-forth.

2. The peculiar construction of 'the arms C, applied to the bolts B, and arranged with the tumblers g, to operate in the manner substantially as and forthe purpose set forth.
